African swine fever has spread to 39 communes and wards in Vinh Long Province since the start of 2026, with 179 livestock households affected. Authorities have culled 4,453 pigs weighing over 254 tonnes, and a provincial meeting reviewed prevention measures and proposed three quarantine station sites.
Losses of this scale in Vietnam's Mekong Delta pig herd reduce local pig numbers and lower demand for feed ingredients such as corn and soybean meal, a modest bearish signal for feed demand in the region.
After 175 past bearish disease events, Corn moved a median +0.0% over 5 sessions (51% higher; middle half -1.7% to +1.5%), and +0.6% over 20.
